Lu Shiyan came from an ordinary background, and due to the disparity in their family status, he was never accepted by his mother-in-law, Shen Manyun. His wife, Su Qinghuan, fell into a coma due to massive postpartum hemorrhage. To prevent her from being caught in a dilemma between family affection and love after waking up, he reluctantly signed a divorce agreement, took his newborn daughter alone, and moved to a remote island, raising his daughter by running a squid stall. Four years later, an unexpected cry of "Little Uncle-in-law" disrupted the peaceful life of the father and daughter. With the divine assistance of the cute babies, Lu Shiyan and his CEO ex-wife Su Qinghuan reunited. This time, they would no longer miss each other, rediscovering the happiness belonging to a family under the warm sunshine of the island.
